ShapefileWriter (h2gis-functions 2.2.1 API)

java.lang.Object
- org.h2gis.functions.io.shp.internal.ShapefileWriter

```
public class ShapefileWriter
extends Object
```
ShapefileWriter allows for the storage of geometries in esris shp format. During writing, an index will also be created. To create a ShapefileWriter, do something like
GeometryCollection geoms; File shp = new File("myshape.shp"); File shx = new File("myshape.shx"); ShapefileWriter writer = new ShapefileWriter( shp.getChannel(),shx.getChannel() ); writer.write(geoms,ShapeType.ARC); This example assumes that each shape in the collection is a LineString.
